Droplet Deformation under Conditions of Neutral Buoyancy

Abstract One of the classical problems hydrodynamics is problem droplet deformation in state neutral buoyancy under action an external force. It assumed that if size initially equal to or less than capillary diameter, it takes shape a regular sphere, regardless density gradient environment and droplet, degree their mutual solubility, possibility Marangoni convection, time elapsed since creation system liquids. To elucidate influence these unaccounted factors as well initial we experimentally studied evolution large-diameter droplets solution with stratification. The behaviour was case when took form spheroid flattened vertically gravity. interferometer used visualize distribution concentration near drop. dependence ratio vertical horizontal diameter on average surrounding medium determined.
